Tire tread



FIG. 1 is a perspective view of a tire tread showing my new tread design, it being understood that the tread pattern, as shown in FIG. 1, is repeated over the outer circumference of the tire and the tread shoulder; and,

FIG. 2 is an enlarged fragmentary plan view of a portion of the tread of my new design as shown in FIG. 1.

The broken line disclosure of a tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
